tried to make this configuration
9600 baud rate
No parity
8 data bits
1 stop bit
No flow control
Connecting a Terminal to the Console Port on Catalyst Switches
Connect a Terminal to Catalyst 2948G-L3, 4908G-L3, and 4840G Series Switches
If you can access the router, type show version at the prompt, and record the configuration register setting. See Example of Password Recovery Procedure in order to view the output of a show version command
Note: The configuration register is usually set to 0x2102 or 0x102. If you can no longer access the router (because of a lost login or TACACS password), you can safely assume that your configuration register is set to 0x2102.
In order to simulate this step on a Cisco 6400, pull out and then plug in the Node Route Processor (NRP) or Node Switch Processor (NSP) card.
In order to simulate this step on a Cisco 6x00 with NI-2, pull out and then plug in the NI-2 card.
Press Break on the terminal keyboard within 60 seconds of power up in order to put the router into ROMMON.
If the break sequence does not work, refer to Standard Break Key Sequence Combinations During Password Recovery for other key combinations.
Type confreg 0x2142 at the rommon 1> prompt in order to boot from Flash.
This step bypasses the startup configuration where the passwords are stored.
Type reset at the rommon 2> prompt.

Hello,
Try changing the baud rate on your hyperterm or whichever terminal emulation you use. Try different options available and see if you can console in.

With Putty, the option to change baud rates is under Connection > Serial -> Speed
Try with the following speeds
2400
4800
9600
19200
38400
57600
115200

19200 grazzie

Glad it worked. Once you are in the device, you can change the speed back to 9600
line con 0
